GiroDisc Porsche 911 GT3/GT3RS/GT2RS (991) w/PCCB (Iron Rotor Pad Shape) Slotted Rear Rotors

The Girodisc system is a direct replacement iron rotor for the OEM PCCB disc, no modifications are necessary. The disc will bolt directly to the car and work with OEM calipers and pads perfectly. 

The central hat section of our rotor is made from strictly U.S. sourced 6061-T6 aircraft specification aluminum.  The disc is made from our own proprietary cast iron, poured in the USA and machined from start to finish in house at Girodisc.  The rotor utilizes a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc.

The rotor and hat have a floating mount system, which utilizes 12 high strength alloy steel drive pins, manufactured by Girodisc in the USA to our own specifications and cadmium plated for a long lasting corrosion resistance. These pins take the load from braking actions while maintaining the axial and radial float between the hat and disc. The pins are secured by class 12.9 cap screws with hardened washers. In order to keep the rotors from making noise when cold, the pins are mounted with anti-noise spring washers on the rotor side which allow the rotor to grow with heat expansion but eliminate the rattle and noise associated with floating rotors. This float also allows the rotor to self center between the pads.

Once the Girodisc system is in place, simply replace the cast iron rotor when needed.

About these Brake Rotors

The GIRODISC GIRA2-154 brake rotor is the disc your brake pads clamp against to slow the car. It turns the car's momentum into heat, so its thickness, flatness and surface condition directly affect how smoothly and consistently your brakes stop you.

Frequently asked questions

What do brake rotors do?

When you press the pedal, the caliper squeezes the pads against the spinning rotor. The friction slows the wheel and the rotor absorbs and sheds the heat that braking produces.

What are the signs of worn brake rotors?

A pulsing brake pedal or a shaking steering wheel when braking, deep grooves or scoring, a raised lip at the outer edge, or blue heat spots. Every rotor has a minimum thickness stamped on it; below that it must be replaced.

Should I replace the pads at the same time?

Yes. New pads should be fitted with new rotors so they bed in together, and rotors and pads are always replaced in pairs on the same axle. On many European cars the pad wear sensor should be replaced as well.

Do I need to break in new rotors?

Yes. Follow the pad maker's bedding procedure, usually a series of moderate stops from speed without coming to a full stop, so an even layer of pad material transfers to the rotor. Clean new rotors of any protective coating before fitting if the maker requires it.

How do I make sure this brake rotor fits my car?

Compare the part numbers listed on this page with the number on your old part or in your vehicle's parts catalog, and check the fitment information. If you are unsure, contact us with your VIN before ordering.
